This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Laney Super Group Emulator

This was a request that came in from Cody from the They Remained Silent blog. It's an emulator of the Laney Super Group 100 watt head designed by Heuller Pinson (MallerMB). I would assume you should bias the JFETs to ~4.5v then adjust from there. Don't have a ton of info on this other than that. This one's laid out for onboard 9mm pots mounted from the solder-side. Cody asked for it to fit in a 125B, but you should be able to squeeze it into a 1590B.

Here's the schematic if anyone wants it.


  1. Sorry for ask:
    This is a pedal to record in line or is a ocb to install the phone and use as amp?

    1. It's just a pre-amp emulator, it won't work as a headphone amp.

  2. Has anyone verified this schematic?
    - it doens't play nice as a vero build

  3. This is laney supergroup 100 ?
